Massive Glass Window Panels Being Installed at Apple Campus 2

With just 12 months to go until Apple's second "spaceship" campus is scheduled to be completed, construction crews are hard at work on the main ring-shaped building and several auxiliary buildings, including the underground auditorium, a visitor's center, and a set of research and development buildings.

Drone pilot Duncan Sinfield today shared another monthly campus update video with MacRumors, giving us a look at how construction has progressed since December. Late last month and early this month, enough of the main building was completed that the unique, curved glass windows could start going up. In the video, you'll see the first window panels on the building, both at the exterior and the interior of the ring.

With construction growing closer to completion, work on the landscape may soon begin. Apple's second campus will feature 80 percent green space, a central garden with outdoor dining areas, and more than 300 species of trees, including a variety of fruit trees. Underground structures like parking facilities and the auditorium will be covered with greenery.

When finished, the campus will include the 2.8 million square foot ring-shaped main building, several parking structures, a 100,000 square foot fitness center, a 120,000 square foot auditorium, and a dedicated visitor's center with an observation deck, cafe, and Apple Store.
